STDA128

SBC Carrier with 3 Module sites and I/O facilities, VME size

Overview

The need for 100% fault-tolerant DSP systems has been a dream for us for a long time. The development of the STDA128 provides a platform for 3-way redundancy. If two out of three STDA128s in a turn-key system become damaged, the functionality of the last STDA128 would ensure that the system would continue functioning with no loss of performance. When a faulty STDA128 is being replaced, the 'live' STDA128 will simply continue un-interrupted. This is only possible thanks to our unique implementation of a distributed and modular DSP concept and the STDA128 can hold three such Modules.

Key Features:

	3-slot Carrier board, VME-sized and fits 6U racks
	On-board DC-DC power supplies convert 24V Input voltages to the 1.5V, 2.5V, 3.3V, 5V & +/-12V required by the Modules
	Three Module sites; One is the Master and interface to the other Modules either via Global Bus access, Comm-ports or the 200MB/sec Digital Bus.
	On board QUAD UART, using the OX16C954
	RS232 or RS422 levels
	2k bytes of EEPROM
	Watch-dog circuits
	On-board 4Mbyte Flash for User programs
	24x TTL I/O signals
	Four LEDs

Benefits

The flexibility of the STDA128 can best be illustrated by the target application, i.e.. control of bearings in a Power Station and the Modules that has been targeted for IO392, but will also work with other Modules.
